Imposition of constraints did not converge


Clicked A Few Times
Dear all,

when doing a torsional energy scan I often get the error below. However I don't get it systematically and all the times.
But is these cases I really can't make it working and it is quite frustrating.
Can't understand the reason and how to solve - can anybody help?


Thanks

MPI_ABORT was invoked on rank 0 in communicator MPI COMMUNICATOR 3 DUP FROM 0
with errorcode -1.

NOTE: invoking MPI_ABORT causes Open MPI to kill all MPI processes.
You may or may not see output from other processes, depending on
exactly when Open MPI kills them.

Could you provide the associated input file?

it is a confidential molecule unfortunately and I can't share it. Any way I can share it confidentially?
